Model Target Generator doesn't succesfully train advanced target #71

Closed ribowcott closed 7 months ago

ribowcott commented 8 months ago

Summarize the bug: When sending an advanced model target to be training, the system does not complete the operation

Observed problem After sending the advanced model target to be trained, the model is uploaded, the system the sits on the "Fetching ETA..." for a while. This then stops without warning and the user is prompted to start training agian. Another attempt results in the same outcome.

Expected result Model target to be trained and the data set to be available in the file system

Other observations Models being used are scan files and uploaded in the .obj file format. Standard Model targets work just fine, it appears to be the training that is the issue.

Reproducible steps Steps to reproduce the behavior:

  1. Upload .obj
  2. Create ADVANCED MT DATABASE
  3. Click 'Train'
  4. See failed result

Affected Vuforia Engine version: v10.18.5

Affected platform:

Affected device:

Affected database CAT.zip CAT-RP2500.zip

Device or platform logs MTG_active.log

Hi there, I'll reach out to our R&D team and check if the logs you shared are sufficient to debug your problem. Thank you for raising this!

Hi there, it seems there's some issue with the object itself. It is recommended to run the input data through a gIFT validator first.

More than happy to run it through a validator. Do you have anything you recommend?

If there is an issue with the model do you know why Vuforia Expert Capture both, accepts the model and produces both a standard and advanced model target without issue?

It seems odd that one works and not the other. I am using the same obj file

That I am not aware of, it could be that both products process the data slightly differently. This validator should be good: https://github.khronos.org/glTF-Validator/.
